Abstract

Drying, especially rotary drying is without doubt one of the oldest and most common unit operation in industry and in this paper, the main process is drying solids, while making the Hot Mix Asphalt used in roads construction. Drying is a very complex non-linear process; we make combination between two dynamic models of dryer plant to solve the drying rate equation which cause the non-linearity of the model. The aim of this research is to improve dryer control by developing control system by designing of an integral variable structure controller, the design of integral sliding surface is determined by the choice of the controllability matrix and the selection of the transfer-function matrix from the reference signal to the Pseudo-output, Appling this VSC to the dryer plant to see the performance, in order to reducing the fuel and air used by the dryer, so that the efficiency of the dryer will increases. This article compare the behavior of the plant dryer when connected with the proposed VSC with the traditional PID controller, The behavior of the control system) has been tested with simulations based on the model of a plant dryer using The Matlab®, and Simulink.
